As you may or may not know, Quebec is infested with puppy mills, where dogs are kept and bred under horrendous and cruel conditions. Pet store puppies come from these places, so stay away from them!
Also walk away from any breeder who uses the words "Tea cup or Toy" to describe their dogs, and any who have not titled their breeders, and do not give guarantees against any genetic defects common to the breed.

If you want a well bred and healthy dog, you may have to wait awhile, travel a good distance, or have one shipped to you.

I know of no REPUTABLE Chi breeder in Quebec. You might want to contact the Chi Club of Canada and ask if they know of any.
